loose bearing race - K/H disc hub

Nobody asked how much 'wobble' the race has. If it has been loose for a long time, there could be a lot of wear. And how would you measure it? If wear is considerable, then three problems present.
- how well will Loc seal a large gap, if it can at all
- how do you centre the race in a hole that could have worn to an oval shape
- runout at the disk pad surface. Off centre 0.005" at the race might be 0.020" or more where the pads apply, giving a pulsating brake pedal.

Get the hub properly machined to take a spacer...or get a new hub.
